TERMINAL SLEEVE non TRAIN `Piras `Inl CONNECTERI HEADS.

-Appneation mea' January 7,' 1922. serial No. 527,568.

iiy invention relates A further purpose is to form along counection between the'head and a removable abutment Jfor the spring pressing the train pipe terminal forward with respect to the head, so that the* abutment can be backed eti to uf'ithdraw the terminal andthe parts may be replaced w nie the cars'aife coupled and the hose is connected' with the train pipe terminal.

; further purpose to enclose the spring the train pipe terminal 'torward 1nv forcing the connecter head within a ren'iovableand adjustable casing carij'ying an abunnentA for i said spring'so-asto attain additional axial length ot threaded connection be' veen'the s without excessive thickness ot' head. 'further purpose isto provide the head with a removable engaging sur-tace surrounding the train pipel terminal.l

A further purpose isto make the engagement ot separate parts of the head withthe meeting parts ot mating heads, in the positions corresponding to the individual ytrain pipe terminals, adjustable not only when the heads are disconnected but even when the heads are connected by reason or" coupling ot the cars. v i Further purposes willappear in the specilicationand in the claims.

phave preferred to illustrateniy invention by but one main form with several slight modifications thereof, selecting l a form which is, practical7 eiiicient, inexpensive and readily adapted to `a ygreat, variety ci heads, and which at the same timewell illustrates the principles ot my invention.

Figurek 1 is a side elevation showing one form of connecter head and mounting therefor to which my inventionl is applicable.

Figure 2 is a broken longitudinal section through the head showing my inventionapH plied thereto, i

toA pipes intended toA be seated in the heads ot automatic conare connected Y shape or to lie on opposite be bolted rto it at 19. The ends of the yoke `Figure 31's a broken longitudinal section showing two vopposed train pipe terminals and theirl correlated parts with the abutment in retracted position, preliminary lto removal or ready forv tighteningA after replacement of the gaskets.

Figure et is a sect1oncorresponding` to' Figure Band showinga slightly modified torni.

VFigure is a corresponding section show` abutment extended ing my` vremovable through the head to malte adjustable that part `ot the head surrounding the gasket.y In the' drawings similarI numerals indicate like parts;r Y i ln order to iv vention is used in'. conjunction with connecter heads which are normally mounted some manner' resilientlytrom brackets to 'relatively fixed train parts, I have shown lone form of y such head and mounting,

though recognizing they tact that the par- 'form of the head andinounting have ticul r not ing" to do with the present invention' forcent the shape of the head or theloca-A tionot the connections with `i"espect to it may cooperatewith the structure ofthe retaining devices tor the terminals to assist Ain application 'ofthe invention vor by their use ot or accessibility of the parts comprising'my invention -Describing the general structure of Figwithout claiming this strucure 1, therefore, ture, and viewing it as for my purpose a generic vmount7 though it is described andv claimed in an application tiled by Edward A. Robinson., for automatic train pipeyconnecters, Ser. "No,v 255,948, tiled February 3, 1920, I show a bracket4 10 having` at its lower end a. threaded split clamp 11 ytightened bybolt 12 about av helical spring 13 llustrateithe fact that my in-v location may rinterfere with the-- which is grippedr within the threads ofthe' clamp. This spring 13 is correspondingly threaded into and grippediby a'split clamp 11i tightened by bolt 15 embraclng the outer end of the spring.v

The split cla'nip'lll yterms port, here shown as of yolre form, and comprising arms 16 and VV17 terminating at dit? ter'ent heights and staggered laterally so as sides kot the head 18 and part ot' a sup-- with turning the` collar independently of' the sleeve terminal 30. 'l

rlhe collar 1s now screwed into its 1ntended position after which i the lock nuts f are moved toi-Ward and locked to radjust the compression 01"' the spring 35,' and the projection of the sleeve and gasket beyond the tace. rlie adjustability ot' the collarwithin the head allows change of the position of the collar it .the desired spring compression-'does Y not coincide with the intended amount ont tion set, the

to retain the sleeve or collar 38 in anyT yposi-YA two adjustment-s `thus permit- 'ting normal spring compression of any desired 'amount withy normaliuncoupled projection to any desired extent. j y

Vln 'Figure `5 the collar is extended to form not only a long threaded engagement n the head', receiving a partot the length ot the spring, but is further extended to the liront oit the head to term' also the guide l tor the enlarged portion 32, of ,the terminal rChis hasa decided advantage in malring the'front ofthe rcollar,effective as the engaging portion o1 4the yhead which meets the corresponding portion of the `mating head; so that 'in case of Wear this collar can be turnedv to vvary the part Vreceiving` the wear, or can be adjusted in order-to give 'or to maintain fthe desiredextent oi pro-l Awear has taken place.

jection, orv can be replaced where excessive By reason ot the independent adjust-- 'lity of the casings formed by these project-ing collars surrounding the individual train pipe terminals, these points ot engagement with adjoining connecter parts canbe set up independently to correct any lack of alignment of the heads. They can be set up to obtain contact and somepressure even when the cars arel coupled, though the pressure present at this time would malre'it difficult to project them to what might "be the preferred positions. 1

lt will be evident that various rchanges may be made by others interested in Obtaining part or all o1c the advantage vot my invention without copying it; and'it is my purpose to include herein all such-changes as come within the reasonable spirit and scope of my invention.
